It is x^2 + xy + y^2
4x cubed y cubed z divided by x negative squared y negative 1 z sqaured = 4
64 x cubed minus y cubed is (4x - y)(16x^2 + 4xy + y^2)
x^3 + y^3 = (x + y)(x^2 - xy + y^2)
(x + y)(x + y)(x + y)
X divided by -Y is the same as -X divided by Y. Or - (X/Y)
4x cubed y cubed z divided by x negative squared y negative 1 z sqaured = 4
( 6x2 / y ) × ( y3 / 12x4) = 6x2y3 / 12x4y = y2 / 2x2
64 x cubed minus y cubed is (4x - y)(16x^2 + 4xy + y^2)
This has infinitely many solutions. The idea is to solve the equation for one of the variables, say for "y". The solution will be in terms of "x" in this case. Then, if you assign any value to "x", you can calculate the corresponding value for "y".
(x + y)(x + y)(x + y)
x^3 + y^3 = (x + y)(x^2 - xy + y^2)

X divided by -Y is the same as -X divided by Y. Or - (X/Y)
Given X:Y, where X and Y are the integers of your ratio, divide both sides by Y. Then you'll have: (X / Y) : (Y / Y) Recognizing that an integer divided by itself is equal to one, (Y / Y) = 1 Finally, you are left with your solution of (X / Y) : 1 Given X:Y, where X and Y are the integers of your ratio, divide both sides by Y. Then you'll have: (X / Y) : (Y / Y) Recognizing that an integer divided by itself is equal to one, (Y / Y) = 1 Finally, you are left with your solution of (X / Y) : 1
You can only get a specific number for an expression if you assign numbers to the variables. As an expression, the existing expression cannot be simplified.
xcubed-1 Answer::(X-1)(Xsquared+X+1) when you factor xcubed minus a number its the same thing as x cubed minus y cubed and x cubed minus y cubed factors to:: (x-y)(xsquared+xy+y squared) the first factor, (x-y), is the cubed root of the first and the cubed root of the second, so in the answer i have (x-1), which is x cubed minus one cubed :) the second factor, (xsquared+xy+ysquared), you take the first number squared, Xsquared, then the first and second one multiplied together, XY, and then the second number squared, Ysquared, so in the answer i have (xsquared+x+1), which is x squared, then x times 1 which is just x, and positive 1, which is negative 1 squared :) x^3 - 1
